What is edge blending

Historically, edge blending was the ‘art’ of blending multiple projectors into a single seamless image. Scalable has moved the ‘state of the art’ into science.

Edge blending is used to create wide screen seamless displays and displays on screens of non-traditional shapes such as domes, cylinders, toroids and articulated surfaces.

The challenge

When projected images overlap, there is a region of elevated brightness where the intensity must be toned down. Our advanced algorithms calculate the precise values required to fade the pixels as they transition from one projector to the next.

The process of edge blending involves manipulation of individual pixels to ensure perfect intensity in the blend zone. The process involves precise algorithms which measure intensity of the projectors and then fade from full intensity to zero over a specified blend zone. The result is a perfect seamless display.

Edge blending is a term which has matured over time. In some circles this technology is called “tiled display”, “soft edge blending”, “edge blended”, “seamless display” or “multi-projector” displays. We have found that the perfection of the science comes with years of experience.
